BackgroundThis document has been developed to guide physiotherapists working in acute care who utilise Cough Assist, inspiratory muscle training, manual and ventilator hyperinflation and who perform induced sputum procedures. Key ObjectiveTo ensure the delivery of safe, evidence based, best practice respiratory management in adult and paediatric patients by acute care physiotherapists.Back to Table of ContentsScopeThis document applies to the following staff working within their scope of practice:Physiotherapists Nursing staff Physiotherapy students under direct supervisionCarers trained or under instruction/prescription by physiotherapists.Back to Table of ContentsSection 1 – Cough assist to enhance pulmonary secretion clearanceThis section pertains to usage of the Emerson CA-3200 cough assist machine and the Phillips Respironics Cough Assist E70, in suitable adult and paediatric patients at the CHHS, who have the problem of retained secretions and an ineffective cough. The cough assist machine (CAM) is an optional adjunct to standard physiotherapy treatment.Background Coughing is an essential reflex which clears excess secretions and foreign matter from the airway. The essential components include deep inspiration, closure of the glottis and forceful expiration. In order for a cough to be effective, an adequate expiratory flow must be generated. A normal peak expiratory flow is in the range of 6-12L/sec ADDIN EN.CITE <EndNote><Cite><Author>Irwin</Author><Year>1998</Year><RecNum>1219</RecNum><DisplayText><style face="superscript">1</style></DisplayText><record><rec-number>1219</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1503634836">1219</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Irwin, R.

Cough strength can be reduced in patients with inspiratory and expiratory muscle weakness, leading to low lung volumes and difficulty clearing secretions2. Mechanical insufflation-exsufflation (in-exsufflation) via a CAM can assist in the removal of pulmonary secretions without the need for more invasive techniques such as open (guedel or nasopharyngeal) airway suctioning. Mechanical in-exsufflation consists of insufflating the lungs with positive pressure, followed by a quick change to negative pressure exsufflation. This creates a peak and sustained flow high enough to mimic a cough and thereby to loosen and move secretions toward the oropharynx for suctioning or expectoration ADDIN EN.CITE <EndNote><Cite><Author>Homnick</Author><Year>2007</Year><RecNum>1220</RecNum><DisplayText><style face="superscript">2</style></DisplayText><record><rec-number>1220</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1503635071">1220</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Homnick, D.

This includes multiple rib fractures and flail segmentsPatients with cardiac compromise as increased thoracic pressures in the insufflation phase can reduce cardiac outputFacial fractures, facial trauma, sinus surgery. In this case a mouthpiece may be used as opposed to the facemask in consultation with senior physiotherapist/ medical staff. Equipment and AssemblyEquipmentEmerson CA-3200 Cough Assist machine or Phillips Respironics Cough Assist E70Patient circuit Bacterial/viral filterBreathing hoseConnector Patient interface (face mask, mouthpiece, or tracheostomy adapter)Pulse oximeterTissues or wall suction for sputum clearanceMask/eye protection for staff member if indicated (infection or multi-resistant organism) AssemblyConnect the machine to power and position it within easy reach.Connect the patient circuit to the machine (see Attachment 2). ProcedurePhysiotherapists may only utilise CAM as part of physiotherapy treatment once they have completed the CAM competency package with the appropriate HP3 Physiotherapist (Attachment 3).Identify indications for use of CAM and any precautions or contradictions and select the appropriate interface. If precautions exist, discuss with senior physiotherapist and medical staff prior to initiating cough assist. If the CAM is being used with a spinal cord patient, refer to the Physiotherapy - Adult Patient with a Spinal Cord Injury Guideline.Perform hand hygiene, apply personal protective equipment (PPE) and observe any other precautions.Explain the treatment and gain informed consent from the patient/carer. Assess appropriate outcome measures If assessing peak cough flow as indicated. Refer to Attachment 1 or Clinical Guideline: Physiotherapy- Adult Patient with a spinal cord injury, found on the policy register, on how to assess peak cough flow, Attachment 3. Appropriately position the patient to maximise ventilation. Alert: The Emerson CA-3200 does not support oxygen to be entrained into the circuit as it is an electrical hazard. If you need to entrain oxygen use the Phillips Respironics Cough Assist E70Select either automatic or manual mode. This depends on patient presentation but generally: Manual mode will be used for acutely unwell patients where the cough assist is used as a new treatment modality. Automatic mode is used in long term use of cough assist and for those patients with cough assist previously set up for the treatment of a chronic condition. Manual or automatic mode can be used in patients presenting to hospital with acute issues that use the cough assist as a long term treatment at home. This depends on patient presentation at the time of treatment. Titrate pressures delivered to the maximal expiratory and inspiratory pressures as tolerated by the patient by adjusting the machine parameters as per Attachment 4. This needs to be individualised depending on patient presentation. Alert: Tracheostomy/Endotracheal tube (ETT)If using a tracheostomy interface either:inflate cuff and perform treatment place speaking valve/cap over tracheostomy and perform therapy through mouth. Ensure cuff is completed deflated prior to placing speaking valve.Be sure to disconnect the patient from the CAM immediately after the cough cycle and allow adequate rest. Patients with an artificial airway may require higher pressures to achieve therapeutic levels due to the resistance to air flow created by the tube8.Determine the dosage: treatment can involve any combination of deep breaths (insufflations only) and cough/s (insufflations followed immediately by exsufflations) and should be individualised depending on patient presentation and tolerance. In patients with neuromuscular weakness, an attempt to cough should also be encouraged, whereas patients with emphysema should be encouraged to allow passive exsufflation as glottis closure and high intrathoracic pressures are thought to encourage distal collapse and ineffective cough4.If in automatic mode, therapy will commence as per the set parameters once the machine is in therapy mode. If in manual mode, deliver the set dosage of insufflations and exsufflations through the interface using the manual lever or foot pedal on the Philips Respironics Cough Assist E70. Insufflations should be delivered for 3 seconds. Incorporate adjunct techniques such as manual techniques, active cycle of breathing technique, saline nebuliser ADDIN EN.CITE <EndNote><Cite><Author>Liszner</Author><Year>2006</Year><RecNum>1278</RecNum><DisplayText><style face="superscript">4</style></DisplayText><record><rec-number>1278</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1503636623">1278</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Liszner, K.</author><author>Feinberg, M.</author></authors></contributors><titles><title>Cough assist strategy for pulmonary toileting in ventilator dependent spinal cord injured patients.</title><secondary-title>Rehabilitation Nursing</secondary-title></titles><periodical><full-title>Rehabilitation Nursing</full-title></periodical><pages>218-221</pages><volume>31</volume><number>5</number><dates><year>2006</year></dates><urls></urls></record></Cite></EndNote>4 and manual assisted coughPEVuZE5vdGU+PENpdGU+PEF1dGhvcj5XaGl0bmV5PC9BdXRob3I+PFllYXI+MjAwMjwvWWVhcj48

ADDIN EN.CITE.DATA 3,8 as required (see Clinical Guideline: Physiotherapy – Adult patient with a spinal cord injury, on the policy register, attachment 5 for details on how to perform Manual Assisted Cough). Alert: If the foot pedal on the Philips Respironics machine is plugged into the machine the manual lever will be disabled.After a treatment cycle, disconnect the patient from the device (return the patient back to the ventilator, if applicable). Allow time for a normal breathing pattern to return (20 to 30 seconds) to prevent hyperventilation. Alert: The unit Emerson CA-3200 cough assist is designed for Intermittent Operation Only and not for continuous use i.e. not cycled continuously for more than 5 minutes.Clear secretions that may have become visible in the mouth, throat or tracheostomy tube using tissues or suction (e.g. Yankauer, Y- catheter or closed suction system). For sputum clearance, continue sets until outcome measures indicate that sputum has been cleared. If you believe that the treatment is not adequate discuss immediately with the treating team. Perform hand hygiene. Document patient position, mode of delivery, pressure, dosage, outcome measures and ongoing management plan. Alert: Patients who are receiving this treatment may strain a muscle and can complain of soreness or discomfort post therapy. If this is the case, refer to the medical team for review. Treatment may need to be ceased it the pain is too severe.Cleaning and Maintenance ADDIN EN.CITE <EndNote><Cite><RecNum>1221</RecNum><DisplayText><style face="superscript">7</style></DisplayText><record><rec-number>1221</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1503635515">1221</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors></contributors><titles><title>Emerson 3200 User Manual</title></titles><dates></dates><urls><related-urls><url> mask and tubing require cleaning. The bacterial filter can be left in place as long as it is not blocked by sputum or trapped moisture. If it is soiled it will need to be replaced. Replace the mask, tubing and filter when there are obvious signs of wear and tear. The mask can also be replaced when it is no longer possible to get a good seal.Daily Cleaning:Wipe down the interface with a clean detergent wipe. If the circuit is visibly soiled (for example, with sputum), wash the tubing as per the instructions below.Weekly Cleaning:Wash the tubing and mask in warm soapy water and allow to air dry. The mask can be left to dry in the patient’s room on a clean towel. The tubing should be left to dry in a hanging position and must be completely dry before re-use.After final use by the patient, the circuit consisting of tubing, patient interface, adapters and bacterial/viral filter is disposed of. The patient circuit cannot be sterilised for reuse.If the device is to be used by more than one patient concurrently, the circuit including the tubing, patient interface, adapters and bacterial/viral filter must be replaced between patients to prevent cross contamination. The exterior of the machine is to be wiped down with a mild detergent and water, detergent wipes or with a bactericidal cleaning solution such as 70% isopropyl alcohol. Back to Table of Contents Section 2 – Inspiratory Muscle Training Inspiratory muscle training (IMT) increases the strength and endurance of the inspiratory muscles (diaphragm and accessory muscles). This treatment is relevant to 3 main groups of patients at CHHS:Chronic Obstructive Pulmonary Disease (COPD)Chronic Heart Failure (CHF)Intensive Care patients who have been mechanically ventilated for > 7 days.This section provides guidelines for IMT to assist patients to:Increase inspiratory muscle strength and enduranceFacilitate weaning from mechanical ventilation (Intensive Care Unit (ICU) patients)Improve patient quality of lifeReduce dyspnoeaImprove exercise tolerance.BackgroundIMT has been shown to improve respiratory muscle strength, endurance, exercise performance and quality of life, and reduce dyspnoea, in individuals with inspiratory muscle weakness and poor exercise tolerance (e.g. COPD ADDIN EN.CITE <EndNote><Cite><Author>Shoemaker</Author><Year>2009</Year><RecNum>10</RecNum><DisplayText><style face="superscript">9</style></DisplayText><record><rec-number>10</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1285416116">10</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Shoemaker, M.

ADDIN EN.CITE.DATA 12, and is relevant to both ICU patients (both ventilator-dependent and recently weaned) and patients with acute exacerbation of COPD towards the end of their inpatient stay. The ‘chronic’ IMT protocol is based on evidence in stable community-dwelling patients with chronic COPD and is more suitable in a pulmonary rehabilitation context. The chronic approach can also be applied to patients with stable congestive heart failure.Acute IMT Program:IndicationsVentilated ICU patients (> 7 days) that are alert and are able to actively participate with training but have failed to wean from mechanical ventilation by usual strategies (e.g. decreasing pressure support or t-piece trials)ICU patients recently weaned from mechanical ventilation > 7 days who are breathing spontaneouslyPatients admitted to the respiratory ward with an acute exacerbation of COPD, where a goal is long-term management of dyspnoea. Note: Patients are only suitable when the acute exacerbation is resolving and they are no longer distressed at rest. Ideally, prescription of IMT should occur in the 1-3 days prior to discharge, with the patient to continue independently following discharge.Patients are not suitable for IMT if the patient:cannot actively participate or communicate (gestures, pointing or mouthing words)is younger than 16 years of ageis pregnantunstable in any way (e.g. cardiovascular, neurological)requires excessive ventilatory support (e.g. positive end expiratory pressure (PEEP) > 10 cm H20 or fraction of inspired oxygen (FiO2) > 0.6 or are critically PEEP-dependenthas severe dyspnoea at rest orthe medical or physiotherapy staff deem the risks of brief disconnection from ventilation to be unacceptable for any reason.EquipmentAlcohol based hand rub Threshold Inspiratory Muscle Trainer device (Phillips Respironics): allows incrementally adjusted training pressures from 9cmH2O up to 41cmH2O pressure (refer to Figure 1)Figure 1. Threshold IMT deviceFlexible connector (ICU equipment store) for ICU patients with an ETT or tracheostomy.ProcedureIMT is only performed by physiotherapists who have completed the IMT Competency Package (see Attachment 5). IMT is initiated by the Health Professional (HP) level 3 Physiotherapist and may be performed by HP level 1-2 physiotherapists and physiotherapy students under supervision.Perform hand hygeine.Training should be conducted with the patient in high sitting position, preferably in a chair (Figure 3).For a spontaneously breathing patient, attach the mouth piece to the IMT device and apply the nose peg if the patient tends to breathe through their nose (optional). For a ventilator-dependent patient, attach the flexible tubing to the Threshold IMT. This will allow the Threshold IMT to attach directly to the tracheostomy/ETT (no mouthpiece required) (Figure 2). Figure 2: Attaching IMT device to ETTAdjusting intensity: If Negative Inspiratory Force (NIF) or Maximum Inspiratory Pressure (MIP) testing is available, intensity should be set at 50% of maximum effort to begin with. To adjust the pressure indicator to the setting prescribed, align the red edge of the pressure indicator by turning the control knob at the bottom of the Threshold IMT. The higher the number, the greater the resistance and effort required. If no NIF/MIP testing is available, the physiotherapist should aim for the highest tolerable intensity for a 6 breath sequence (achieved through trial and error).The intensity of resistance is adjusted incrementally between sets by the physiotherapist to ensure patient can just complete the 6th breath in each set.The patient inhales through the device to generate an inspiratory pressure greater than the indicated threshold pressure setting to compress the spring and open the poppet valve.The inspiratory pressure should be maintained for at least 1 second, with respiratory rate < 30 bpm. Audible air flow indicates a successful breath.The patient exhales through the training device via a low resistance one-way valve.Training sessions consist of 5 sets of 6 training breaths for a total of 30 training breaths per day. IMT should be conducted once per day, ideally in the morning, 5 days per week. Including rests between sets, this should take less than 10 minutes per day.If ventilator-dependent, patients are returned to mechanical ventilation for rest between training as needed. If spontaneously breathing, allow rests between sets as required (typically < 1 minute)The patient’s clinical parameters and response during training should be monitored if ventilator-dependent (i.e. Blood Pressure (BP), Heart Rate (HR), Respiratory Rate (RR), and SpO2 (peripheral capillary oxygen saturation)). Otherwise, monitor SpO2 and RR if oxygen-dependent (noting that supplemental oxygen is not required during IMT breaths) ADDIN EN.CITE <EndNote><Cite><Author>Bissett</Author><Year>2012</Year><RecNum>157</RecNum><DisplayText><style face="superscript">20</style></DisplayText><record><rec-number>157</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1285722268">157</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Bissett, B., Leditschke, I.A., Green, M.</author></authors></contributors><titles><title>Specific inspiratory muscle training is safe in selected patients who are ventilator-dependent: A case series.</title><secondary-title>Intensive and Critical Care Nursing</secondary-title></titles><periodical><full-title>Intensive and Critical Care Nursing</full-title></periodical><pages>98-104</pages><volume>28</volume><dates><year>2012</year></dates><urls></urls><electronic-resource-num>10.1016/j.iccn.2012.01.003</electronic-resource-num></record></Cite></EndNote>20 Guidelines for ConcernPulse Oximetry Saturation decreases >5% from baseline Subjective signs of distress or severe sharp pain on inspirationCardiac arrhythmiasSigns and symptoms of secretion retention in ventilated patients – provide suction if indicated.Outcome/Progression MeasuresContinue training with the acute plan until patients have reached goal inspiratory muscle strength (eg MIP of 80 – 100 in previously well patient). This may include independent IMT at home following discharge from hospital.In patients with COPD, consider switching to chronic IMT approach after 6-8 weeks for maintenance.Patient EducationPatients/family/nursing staff should be carefully instructed on rationale for IMT, precautions and guidelines for treatment.DocumentationAll documentation should follow the Clinical Record Documentation Procedure. However with respect to IMT, the following should be specifically mentioned:Informed consent, see Consent and Treatment Policy on the policy register.Training Parameters used (resistance, sets, breaths)Response to treatment (any adverse outcomes).Cleaning Of EquipmentEquipment used for inspiratory muscle training is single-patient use only and disposable, therefore no cleaning or sterilising is required.Threshold IMT DeviceThe Threshold IMT device is for single patient use only. It should be stored in the patient’s bedside trolley with the patient’s sticker on it and can be used following discharge should the patient wish to.Chronic IMT Program ADDIN EN.CITE <EndNote><Cite><Author>Hill</Author><Year>2010</Year><RecNum>283</RecNum><DisplayText><style face="superscript">21</style></DisplayText><record><rec-number>283</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1288523905">283</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Hill, K.</author><author>Cecins, N.

ProcedureTraining should be conducted with the patient in high sitting position, preferably in a chair with upper limbs supported (Figure 3).Figure 3. Position for IMTAdjusting intensity: intensity (target load) should be titrated to 30% of MIP to begin with. To adjust the pressure indicator to the setting prescribed, align the red edge of the pressure indicator by turning the control knob at the bottom of the Threshold IMT. Attach the mouth piece to the IMT device and apply the nose peg. The patient inhales through the device to generate an inspiratory pressure greater than the indicated threshold pressure setting to compress the spring and open the poppet valve. Audible air flow indicates a successful breath.Training should follow the pattern of 7 lots of 2 minute cycles, where target training equals 30% of MIP, and the warm-up load is 15% of MIP. Intensity should be increased as tolerated to maintain an RPE of 13-14 / 20 (or 4/10). IMT should be performed 3 days a week for a minimum of 8 weeks, and then continued indefinitely at 2 days a week for maintenance.Guidelines for ConcernPatient reports in sudden sharp pain on inspiration (refer for medical review, due to risk of pneumothorax)Outcome/Progression MeasuresRecommend monitoring SpO2 and RR during initial training session Review progress with MIP after 8 weeks of training – if no changes, cease IMT. If patient has improved, continue with maintenance program for life (2 sessions/week).Cleaning Of EquipmentEquipment used for IMT is single-patient use only and disposable, therefore no cleaning or sterilising is required.Back to Table of Contents Section 3 – HyperinflationBackgroundHyperinflation is the delivery of a slow, deep inspiration greater than baseline tidal volume up to a peak inspiratory pressure (PIP) of 40cm H2O, followed by an inspiratory hold of up to three seconds, and a quick, unobstructed expiration to patients with an artificial airway22. The slow deep inspiration to 35-40cm H20 re-expands areas of atelectasis23, the inspiratory hold recruits lung segments via collateral channels, allows for gas exchange and mobilises secretions, while the quick release increases expiratory flow rates, allows for annular two phase gas liquid flow, and mimics a huff and/or cough, mobilising pulmonary secretions from distal to proximal lung segments24. Hyperinflation has been shown to be an effective technique for mobilising sputum25-27 reversing atelectasis28, 29 improving oxygenation and pulmonary compliancePEVuZE5vdGU+PENpdGU+PEF1dGhvcj5OdG91bWVub3BvdWxvczwvQXV0aG9yPjxZZWFyPjE5OTg8

ADDIN EN.CITE.DATA 25,30. Traditionally, hyperinflation has been delivered to mechanically ventilated patients by disconnecting them from the ventilator and connecting them to a manual resuscitation circuit and is known as manual hyperinflation (MHI). At CHHS, the technique is delivered via the Laerdal Silicone Resuscitator bag (Figure 4). Disadvantages of this technique include loss of PEEP, de-recruitment of lung segments, and poor tolerance or dyssynchrony with the technique by agitated patients. When completed manually, substantial clinical experience is required to deliver the technique consistently and to prevent barotrauma or volutrauma31. Ventilator Hyperinflation (VHI) is the delivery of hyperinflation breaths via adjustments of ventilator settings and when compared to MHI, VHI has been shown to be as effective in mobilising secretions, improving lung compliance, oxygenation and restoring lung volumes32-35. It requires no disconnection from mechanical ventilation, so there is no loss of PEEP and it is synchronous with patient breaths. Volumes are delivered consistently and PIP and volume are controlled by the ventilator, thus reducing the risk of barotrauma or volutrauma in appropriately selected patients.In clinical practice, VHI is utilised in patients currently undergoing mechanical ventilation while MHI is mainly utilised in patients no longer requiring mechanical ventilation.

If precautions exist, discuss with appropriate senior physiotherapy staff and treating Consultant/Senior Registrar prior to initiating MHI.Ensure appropriate number of staff are available to carry out the treatment. Physiotherapists with less clinical experience or who have not performed the technique recently should consider a second staff member (nurse or physiotherapist) to be available to suction and place the ventilator on standby in the more unstable patient. For patients on vasoactive infusions or who have ICP monitoring, MHI should be carried out with the bedside nurse present as titration of infusions may be required during treatment. A second physiotherapist is required if manual techniques are indicated as an adjunct to MHI. Explain the treatment to the patient. Appropriately position the patient to maximise ventilation and perfusion (V/Q) matching and to drain secretions.To set up the MHI circuit (Figure 5), attach a HME filter to the Laerdel bag. For ventilated patients, ensure a PEEP valve set at the patient’s baseline PEEP setting is incorporated into the circuit. Figure 5. Circuit set up for the ventilated patientAttach the oxygen tubing to the oxygen outlet and turn the oxygen flow to 15 litres/minute. Ensure the reservoir bag is not split and is filling with gas. A manometer is not required to be used as the Laerdel circuit has a safety valve that prevents PIP from exceeding 35 cm H2O26.For the ventilated patient, silence the ventilator, disconnect the ventilator from junction of the Bennet’s connector and connect the patient to the Laerdel circuit. For the self-ventilating tracheostomised patient, disconnect oxygen and attach the Laerdel circuit to the tracheostomy via the flexible connector only (Figure 6).Figure 6. Circuit connection for the ventilated patientCommence hand ventilating the patient at the same rate and volume as baseline. Once satisfied that the patient is ventilating, place the ventilator in standby mode as per Physiotherapy Ventilator Assessment Tool (Attachment 7) and attach the ventilator to the test mence MHI with a two handed technique, delivering a larger than baseline tidal volume, an inspiratory hold and a quick release ADDIN EN.CITE <EndNote><Cite><Author>McCarren</Author><Year>1996</Year><RecNum>1329</RecNum><DisplayText><style face="superscript">44</style></DisplayText><record><rec-number>1329</rec-number><foreign-keys><key app="EN" db-id="s9xwzdvpn29ewsertap5wvdb99fred5p200v" timestamp="1503640354">1329</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>McCarren, B.</author><author>Chow, C.

ADDIN EN.CITE.DATA 32,39. For sputum clearance, continue MHI if patient is stable until outcome measures indicate that sputum has been cleared.For all patients, monitor HR and SPO2 throughout. If available, monitor MAP, electrocardiogram (ECG), ICP and Cerebral Perfusion Pressure (CPP). ICP should remain below target, and CPP should remain >60 mmHg (CPP=MAP-ICP). Modify or cease treatment as appropriate.Suction the patient as indicated.Once treatment is complete, for ventilated patients restart the ventilator before reconnecting the patient and ensure the patient is ventilating at baseline or appropriate respiratory rate and with adequate tidal volumes and End Tidal Carbon Dioxide (ETCO2) prior to putting the Laerdal bag away. For ward patients, return patient to previous oxygen circuit e.g. humidified or Swedish nose.Reassess outcome measures and reposition patient appropriately.Document patient position, level of PEEP (if applicable), duration of MHI, appropriate outcome measures and any adverse eventsPerforming VHI Physiotherapists may only perform VHI once they have completed the Hyperinflation Competency package and ventilator training package with the appropriate HP Level 3 or above Physiotherapist (Attachments 6 and 7). The bedside nurse must be present during VHI.Identify indications for VHI, most appropriate mode of ventilation to deliver. hyperinflation for the specific patient, and any precautions or contraindications. If precautions exist, discuss with appropriate senior physiotherapy staff and treating Consultant/Senior Registrar prior to initiating VHI.Alert: VHI can only be performed in SIMV-Volume Control on the GE Carescape Ventilator. Explain the treatment and gain consent from the patient/carer and inform the bed side nurse. Appropriately position the patient to maximise ventilation and perfusion (V/Q) matching and to drain secretions.Adjust ventilator alarm limits (refer to Attachment 8).Adjust ventilator settings to achieve hyperinflation breaths (refer to Attachment 8). Titrate settings during treatment as required to maintain PIP at 35-40 cm of H20.Once target PIP is reached, manual techniques (i.e. percussion or vibration) may be incorporated if indicated.Monitor HR, MAP, ECG and ETCO2 throughout. If measured, ICP should remain below target, and cerebral perfusion pressure should remain >60 mmHg (CPP=MAP-ICP). Modify or cease treatment as appropriate.For patients who may require breaks during treatment due to intolerance of the technique or to prevent haemodynamic instability, return them to their baseline settings in that mode of ventilation. When resuming hyperinflation breaths, the determined values required to reach PIP of 40cmH2O can be resumed without the gradual increase in settings.Suction the patient as required.Dosage - The literature recommends six sets of six VHI breaths to treat atelectasis and improve compliance32,33,38. For sputum clearance, continue VHI if patient is stable until outcome measures indicate that sputum has been cleared.Once treatment is completed, return ventilator settings to baseline return patient to previous mode of ventilation and return alarm settings to previous limits. Inform the bedside nurse that alarm limits and ventilator settings are at baseline. Ensure patient is ventilating at adequate rate, Vt and ETCO2 prior to reassessing outcome measures and repositioning the patient as required.Document the patient position, mode of ventilation, RR, PIP reached, Vt reached, duration of treatment and any adverse events.Back to Table of ContentsSection 4 – Induced Sputum CollectionThis section outlines the processes for receipt and management of referral and safe collection of an induced sputum sample through inhalation of hypertonic saline.BackgroundThe inhalation of hypertonic saline solutions via an ultrasonic nebuliser has been shown to induce production of small amounts of secretions from the airways in patients who are not able to expectorate sputum. The mechanism of this process is not fully understood though hypothesised that increased osmolarity of bronchial lining fluid increase vascular permeability in the bronchial mucosa and production of mucus by submucosal glands. Induced sputum is used in the diagnosis of pulmonary Tuberculosis (TB) and Pneumocystis Jirovecii Pneumonia (PJP), formally known as Pneumocystis Carinii Pneumonia (PCP) 39. Current guidelines suggest that for PJP a single sample needs to be induced for testing. For TB, three samples on consecutive days are required to increase sensitivity of the test40, 41. These can be either spontaneous sputum samples or induced samples. There is evidence to suggest that airway clearance techniques such as percussion and vibrations have no benefit in inducing sputum42.Precautions/Contraindications43 Inadequate respiratory reserve or acute respiratory distressInability to follow instructionsFiO2 >50%Haemoptysis of unknown originUnstable cardiovascular statusThoracic, abdominal or cerebral aneurysmsFEV1 <1.0 LitresPneumothoraxPulmonary emboli.Referrals - generalReferral for induced sputum collection will be accepted from a Medical Specialist/VMO from Intensive Care, Respiratory, Oncology, Haematology or Infectious Diseases only.For inpatients, referral must be documented in the patient’s clinical file, including the purpose for collection. The medical team is to contact the ward physiotherapist via pager to alert them to the referral as soon as possible.Requests are accepted during standard business hours (excluding special circumstances). Refer to “Weekends/out of business hours” for details. For outpatients, a written referral (including patient contact details) will be sent to: Physiotherapy Department Building 15, Canberra Hospital, Yamba Drive Garran 2605, or faxed on 62443692, with a pathology form attached.Alert: If induced sputum is requested for conditions other than TB and PCP, this must be discussed by the treating consultant with a senior physiotherapist.Weekends/out of business hoursMicrobiology is unable to routinely process an induced sputum sample on weekends or public holidays. If the testing is urgent then the requesting medical team will contact the Microbiologist on-call to ensure availability of laboratory staff prior to referral to the physiotherapist for collection.PCP collection requests made over a weekend/Public Holiday will be collected as soon as possible and sent to Microbiology, even if they are unable to be processed over the weekend, to allow for higher diagnostic yield.Requests made for collection after 3.30pm will be delayed until the following business day due to the time taken to collect and process.The physiotherapy evening service (5pm-9pm) will not routinely perform induced sputum collection.SafetyTo minimise the risk of transmission of airborne disease:All induced sputum collections are to be completed in a single room with adequate room ventilation. Refer to attachment 9 for list of appropriate rooms.PPE is compulsory during collection including gown, gloves, goggles and fine particulate respiratory mask.All staff performing a TB collection are required to have a baseline Mantoux test or Tuberculin Skin Test (TST) with CHHS Department of Respiratory and Sleep Medicine (DRSM), which requires 12 monthly updates/reviews.The physiotherapist conducting the procedure will remain with the patient.Should the patient be required to leave the ward for collection then a nurse escort may be required at the discretion of the Clinical Nurse Consultant (CNC) (depending on the patient’s acuity).Alert: It is recommended that bronchodilators and anti-emetics are charted prior to commencing sputum induction due to risk of bronchospasm and nausea. It is recommended that known asthmatic patients have a bronchodilator prior to collection to minimise the risk of bronchospasm and airway compromise44.PreparationOn referral for an induced sputum, the following preparation is required:Referring medical team:inform ward CNC and patient flow unit of the need for the patient to be in a negative pressure roomcontact microbiology if outside normal business hours to ensure sample able to be processedChart 6% Hypertonic salineChart bronchodilators and anti-emetics if required.The ward CNC/Team Leader:Ensure that a negative pressure room is available on the treating wardIf a negative pressure room cannot be organised on the treating ward, liaise with Patient Flow Unit to source a negative pressure room on another ward. Refer to attachment 9 for a list of appropriate rooms. Physiotherapist:Arrange a room for outpatient collections.Ensure all equipment required is available.EquipmentSuchatzki Ultrasonic nebuliser and one-way mouthpiece, including disposable items:bacterial filtermedicine cupdust filter6% Hypertonic saline solution (in premix 10ml sachet)44,45,46 PPE including gown, gloves, goggles and high particulate respiratory maskSputum specimen jarTissuesSterile waterPulse oximeterProcedureGain informed consent from the patient, as per Consent and Treatment Policy on the policy register.Access negative pressure room for collection. If using the room solely for collection purposes, drape a sheet over where the patient will be sitting.Administer bronchodilators and supplemental oxygen if indicated.Perform hand hygiene and don PPE.Explain the procedure to the patient what to expect.Ensure patient is comfortable and in a sustainable position.Perform baseline observations (SpO2, RR and auscultation).Prepare nebuliser with 10ml hypertonic saline solution in disposable cup, and sterile water in the main water chamber up to the recommended marked ‘fill’ line. Refer to Attachment 10 for machine setup. Instruct patient to breathe slowly and deeply.After 5 minutes of inhalation, if no spontaneous cough has occurred, instruct patient to cough. Repeat at 5 minute intervals until a sample is produced44-46. Continue to monitor patient throughout procedure.After 30 mins if no sample obtained, cease the procedure and inform medical team.Repeat observations and ensure patient is stable.Document result of collection attempt in the patient’s clinical record, and data collection of the attempt in the Physiotherapy record book for Induced Sputum.If successful, label sample as “Induced Sputum” and send with pathology form to Microbiology. Refer to Attachment 11 if procedure is unsuccessful. If used, place any draped sheets into the linen skip.Dispose of consumables in yellow bin outside the room.The room requires cleaning before use by another patient. Leave the room vacant for one hour and then contact the cleaning service to clean the floors, walls and furniture with detergent and water. Clean the machine as below.Alert: Morning sample collection is preferable as they are more sensitive for detecting TB47 CleaningWipe nebuliser with soap impregnated wipe Tubing and water vessel are sent to DRSM for thermal disinfection and air dried.Mouthpiece and one way valve are sent to Gastroenterology & Hepatology Unit for sterilizationFilters and the medicine cup are disposable after each test.Back to Table of Contents Implementation This guideline will be implemented via the following:Available for reference to all CHHS Physiotherapy staff and Physiotherapy students via the policy register on SharePoint.Distribution at department communication and team meetings.Inclusion in staff munication with key stakeholders and workgroups.Monitoring through peer review, documentation audits and clinical practice audits.Back to Table of ContentsRelated Policies, Procedures, Guidelines and LegislationPoliciesWork Health and Safety PolicyConsent and Treatment PolicyClinical Records Management PolicyProceduresCHHS Healthcare Associated Infections Clinical ProcedureCHHS Patient Identification and Procedure Matching PolicyAdult Nebulisation Therapy ProcedureInhaled Bronchodilator Delivery for Adults OnlyClinical Record Documentation ProcedureGuidelines Physiotherapy – Adult Patient with a Spinal Cord InjuryTracheostomy Management Adult PatientsClinical Supervision for Allied Health CliniciansCredentialing and Defining the Scope of Clinical Practice for Allied Health ProfessionalsOxygen Therapy and or Non-Invasive Ventilation PaediatricsPhysiotherapy – Adult Patient with a Spinal Cord InjuryLegislationHealth Records (Privacy and Access) Act 1997Human Rights Act 2004Work Health and Safety Act 2011Back to Table of ContentsReferences ADDIN EN.REFLIST 1.Irwin RS, Boulet LP, Cloutier MM, et al.
